Application filed. September 29, 1909, Serial No. 520,178. Renewed. September 26, 1914. Serial No. 863,782.

To all whom it may concern:

Be it known that 1, CHARLES N. GALLAND, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Color- Printing Attachments for Printing-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to printing presses and is in the nature of an improvement of the device disclosed and claimed in the joint application of Asa P. Brooks and myself Charles N. Galland, S. N. 504,363, filed of date June 25, 1909, entitled Color printing attachment for printing presses.

The invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a plan view, with some parts broken away, showing the improved printing attachment applied to a cylinder press of standard construction; Fig. 2 is a detailed view in side elevation, showing the inking mechanism; Fig. 3 is a fragmentary section on the line a m of Fig. 1. Fig. 4: is a side elevation of one of the printing wheels; and Fig. 5 is an enlarged section on the line 00 m of Fig. 4.

Of the standard parts of the cylinder press, it is only necessary, for the purposes of this case, to note the main cylinder 1 and a large spur gear 2 which is carried thereby, being in practice secured to the shaft, not shown, of the said cylinder. This press is assumed to be the same press which is somewhat more fully shown inthe said prior application above identified.

The numeral 3 indicates a transverse countershaft which constitutes a part of the at tachment and is provided with a spur gear 4: that meshes with the spur gear 2. This shaft 3, in this application as in the prior application, is journaled 1n bearlngs 5 adjustably mounted in the bifurcated ends or arms 6 pivotally connected by bolts 7 to arms 8 which, in turn, are rigidly secured to portions of the side frames of the machine; and, furthermore, said shaft is journaled in the intermediate portions of a pair of laterally spaced lever-like bearing frames 9, the lower ends of which are pivotally connected to arms 10 also fixed to portions of the side frames of said machine in the manner disclosed in said prior application. Rigidly secured to the shaft 3 between the bearing frames 9 is an auxiliary printing cylinder or drum indicated as an entirety with the numeral 11. This cylinder is or may be of the construction described in the said prior application and the type Y, mounted on the periphery thereof, may be held by the means disclosed in the said prior application or by any other suitable means. The principal feature of this invention consists in providing, in connection with this auxiliary printing cylinder, supplemental type-holding or printing wheels which may be arranged on either or on both sides thereof. These type-holding wheels 12, in some instances, may be segmental but they are preferably made complete and are provided with endless peripheral channels 13 adapted to hold type Y Within the channel 13, at one side thereof, is an annular type clamping ring 1 1 adapted to be pressed against the type by circumferentially spaced set screws 15 screwed through one flange of the typeholding Wheel. Projecting into the type channel 13 from the other flange of the wheel is an annular rib 16 adapted to engage notches in the type Y The hubs of the wheels 12 are slidably mounted on the shaft 3 and are preferably provided with set screws 17 for securing the same in difierent lateral adjustments in respect to the auxiliary cylinder 11. All of the wheels 12 are held against rotary movement in respect to the auxiliary printing cylinder 11, even when loose on the shaft 3, by a long transverse alining rod 18 passed through alined perforations in the said auxiliary cylinder 11 and in arms of the said printing wheels 12. This alining rod 18 holds the properly set type of the auxiliary cylinder 11 and printing wheels in proper relative positions circumferentially thereof at all times and especially while the said wheels are being adjusted laterally. The lateral adjustments of the Wheels permit a wide variation in range or distribution of the color printing matter on a newspaper. The color printing may be spread out in spaces between the color printing matter by separation of the printing." wheels; from the cylinder and fromeach other. The printing, wheels 12 and the auxiliary printing cylinder: 11' should, of course, be of the same or approximately the same diameter, so that the type carried thereby will properly print on the same surface, to-wit, upon thexpaper carried by the main cylinder 1.v

The inking: mechanism shown, briefly describedgis as follows :1 At their upper and outwardly extended portions, the bearing frames 9' are; rigidly secured to a trough-like ink font 19, one side of which is formed by an ink take-up roller 20 journaled in suitable bearings on the frames. 9' and provided with a ratchetwheel 21 subject to a pawl 22 carried by a roller operating lever 23, which latter is intermediately pivoted on the projecting shaft 20*of the said roller 20. The depending free end of the lever 23 is adapted-to be engaged by an eccentric pin 24 of a gear wheel 25 journaled on one of the frames 9 and meshing with the pinion 26 carried by the shaft 3' of the auxiliary printing roller 11.

At each rotation of the auxiliary printing cylinder 11 and wheels 12, the type are moved against the under surface of an ink delivery roller 27, the shaft of which is mounted in bearing boxes 28 adjustably seated in bifurcated portions of the frames 9. This ink delivery roller is made up of several longitudinally spaced sections or parts separated by grooves 27 located between the auxiliary printing cylinder 11 and the cooperating printing wheels 12. Running in engagement with the roller 27 is a distributing roller 29, the shaft of which, as shown, is detachably mounted in bifurcated arms 30 of the frames 9. An ink transfer roller 31 is loosely journaled in the upwardly projecting arms 32 of a rock shaft 33 loosely journaled in the bearing frames 9 and provided with a depending s1::-ringpressed arm 34 equipped at its lower free end with a roller 35. As shown, the gear wheel 25 is secured on a transverse shaft 36 mounted in the bearing frames 9 and this shaft carries a cam 37 that operates on the roller 35 of the arm 34 and once for each rotation of said shaft forces the transfer roller 31 from engagement with the roller 29 into engagement with the roller 20. The spring 39 attached to the arm 3l normally holds the roller 31 engaged with the roller 29. The ink font or trough 19 is shown as provided with movable partitions l0 that alitne with grooves 27 of the roller 27.

From what has been said, it will be understood that this printing attachment is especially intended for use for printing on newspaper or similar sheet various matter, such as advertisement, incolors different from the color in which the main matter of the paper is printed. In other words, this is intended as a multir-color printing attachment for printing presses having other means for printing the main body portion of the paper.

What I claim is:

1. The combination witha printing press having a paper delivery cylinder, of an auxiliary printing cylinder cooperating with said. paper delivery cylinder, printing wheels axially alined with but laterally spaced from said auxiliary cylinder, said cylinder and: wheels having means for holding type, means for moving said auxiliary cylinder and printing wheels with a common timed action in respect to said paper delivery cylinder, and an inking mechanism comprising a multiplicity of rollers and a single inking trough, said trough having partitions to divide it into compartments for different colored inks, said auxiliary printing cylinder and each of said printing wheels being fed by separate compartments.

2.. The combination with a printing press having a paper delivery cylinder, of an auxiliary printing cylinder cooperating with said paper delivery cylinder, printing wheels axially alined with but laterally spaced from said auxiliary cylinder, said cylinder and wheels having means for holding type, means for moving said auxiliary cylinder and printing wheels with a common timed action in respect to said paper delivery cylinder, and an inking mechanism comprising a multiplicity of rollers and an inking trough, the delivery member of said rollers having a groove and the said trough having a partition, the said groove and partition being alined in a vertical plane that extends between said auxiliary cylinder and one of said printing wheels, substantially as described.

3. The combination with a printing press having a paper delivery cylinder, of an auxiliary printing cylinder coiiperating with said paper delivery cylinder, printing wheels laterally adjacent said printing cylinder and likewise cooperating with said paper delivery cylinder, means for moving said printing cylinder and said wheels in the same relation to the delivery cylinder, and a single inking mechanism for said printing cylinder and said wheels, comprising an ink In testimony whereof I aflix my signaturetrough, a pluraliqi of transfer rollers, and in presence of two witnesses.
